On Friday, an intergovernmental organization hosted a hearing in Boulder, Colorado on the ongoing crisis of missing and murdered Indigenous women in the U.S. That group faces some of the highest violence and sexual assault rates in the nation.

“We are assaulted and murdered by outsiders, by oil workers, by our neighbors, by our partners, and even through the complicity of our federal government due to its laws and enforcement measures,” Lucy Simpson, a citizen of the Navajo Nation and executive director of the National Indigenous Women’s Resource Center, told commissioners from the Organization of American States.

The OAS is a United Nations-like body representing countries in North and South America.

It helps mediate grievances on everything from immigration to drug policy and the political crisis in Venezuela.

Simpson and other speakers also said the U.S. government isn’t doing enough to address the crisis. No one, for example, knows the total number of missing and murdered Indigenous women in the U.S. because federal agencies aren’t really tracking it.

But U.S. Ambassador Carlos Trujillo argued the federal government is doing a lot. Last year, he said the U.S. Department of Justice doubled the amount of grant funding devoted to public safety and victim services across Indian Country.

“The increase in resources together with aggressive investigation and prosecution of crimes shows how seriously the United States takes these issues,” Trujillo said.

Commissioners overseeing the hearing urged the U.S. to work harder on jurisdiction issues between the federal government and tribes.

It was on Thanksgiving night that Eastern Shoshone member Jean Harris’ life took a terrifying turn. She had been waiting for a text from her Northern Arapaho boyfriend of over three years, asking her to come pick him up and bring him home. He’d been staying with his parents for several weeks and she missed him. She put on her clothes, re-applied her makeup and drove from her house in Lander to his parents’ house on the reservation to get him.

Marita Growing Thunder, 19, is sitting in the grass on a warm spring afternoon at the University of Montana campus in Missoula where she studies art. Growing up, she said, her mom was always talking about aunt Yvonne.

The Eastern Shoshone tribe is moving to adopt the Violence Against Women Act in an effort to better prosecute sexual assaults of Native women from the Wind River Reservation. The hope is that the law will help overcome a jurisdiction gap between tribal and federal justice systems.
